What are the different types of neuroblastoma?

Using the following factors, each neuroblastoma is classified into 1 of 4 categories: very low-risk, low-risk, intermediate-risk, or high-risk.

How many stages of neuroblastoma are there?

There are four main stages of neuroblastoma cancers: Stage 1 means the tumour is in one area of the body and hasn’t spread. It can be completely removed with surgery. Stage 2 is divided into 2A and 2B.

Are all neuroblastomas cancerous?

What is neuroblastoma? Neuroblastoma is a very rare type of cancerous tumor that almost always affects children. Neuroblastoma develops from nerve cells in the fetus called neuroblasts. Usually, as a fetus matures and after birth, the neuroblasts develop normally.

Can a baby be born with neuroblastoma?

It is often present at birth, but not detected until the tumor begins to grow and compress the surrounding organs. Most kids affected by neuroblastoma have been diagnosed before the age of 5. In rare cases, neuroblastoma can be detected before birth by a fetal ultrasound.

What are the different stages of neuroblastoma cancer?

There are different stage descriptions for different types of cancer. Once a diagnosis of neuroblastoma is confirmed, how much the tumor has grown and spread is evaluated or staged. The tumor’s stage helps your child’s doctor plan treatment.

Where are neuroblastomas found in the nervous system?

Neuroblastomas are cancers that start in early nerve cells (called neuroblasts) of the sympathetic nervous system, so they can be found anywhere along this system. Most neuroblastomas begin in the abdomen, either in an adrenal gland or in sympathetic nerve ganglia.

How is neuroblastoma treated in the United States?

Neuroblastoma Treatment (PDQ®)–Patient Version 1 A biopsy is done to diagnose neuroblastoma. 2 Certain factors affect prognosis (chance of recovery) and treatment options. 3 There are three ways that cancer spreads in the body. 4 Cancer may spread from where it began to other parts of the body. 5 The following stages are used for neuroblastoma:

How are ganglioneuroblastoma and neuroblastoma alike?

Ganglioneuroblastoma is a tumor that has both malignant and benign parts. It contains neuroblasts (immature nerve cells) that can grow and spread abnormally, similar to neuroblastoma, as well as areas of more mature tissue that are similar to ganglioneuroma.
